Ultrapotent human antibodies protect against SARS-CoV-2 challenge via multiple mechanisms

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is initiated by the trimeric spike protein that decorates the virus and binds the ACE2 receptor. Antibodies against the spike that neutralize viral infection have potential as therapeutics. Tortorici et al. describe two very potent antibodies, S2E12 and S2M11. Electron microscopy structures characterized the binding and showed…
